[RISCV] Add codegen support for RV64A
In order to support codegen RV64A, this patch: * Introduces masked atomics intrinsics for atomicrmw operations and cmpxchg that use the i64 type. These are ultimately lowered to masked operations using lr.w/sc.w, but we need to use these alternate intrinsics for RV64 because i32 is not legal * Modifies RISCVExpandPseudoInsts.cpp to handle PseudoAtomicLoadNand64 and PseudoCmpXchg64 * Modifies the AtomicExpandPass hooks in RISCVTargetLowering to sext/trunc as needed for RV64 and to select the i64 intrinsic IDs when necessary * Adds appropriate patterns to RISCVInstrInfoA.td * Updates test/CodeGen/RISCV/atomic-*.ll to show RV64A support This ends up being a fairly mechanical change, as the logic for RV32A is effectively reused. Differential Revision: https://reviews.llvm.org/D53233 llvm-svn: 351422
